Addressing Clinical Decisions at the Individual Level and Risk at the Employer Level Through the Lens of the Razavi Occupational Health Iceberg

In occupational health, what we see is rarely the whole story.

Fitness-for-Work (FFW) and Return-to-Work (RTW) decisions often appear straightforward: a worker presents with a condition, a medical opinion is issued, restrictions are applied, and work either resumes or does not. These visible outcomes are familiar to workers, employers, insurers, and clinicians alike.

But these outcomes represent only the tip of the iceberg.

Whether that visible tip becomes a story of recovery and stability, or a cycle of recurrence and failure, depends entirely on what lies beneath the surface. This is the premise of the Razavi Occupational Health Iceberg.

The Tip of the Iceberg: What We See in Real Life

Above the waterline sit the things everyone recognizes:

clinical diagnoses, symptom flares, medical notes, temporary work restrictions, modified duties, or time away from work. In the case of occupational dermatitis, this may present as inflamed hands, discomfort, reduced tolerance to tasks, and a recommendation to “avoid wet work” or “limit glove use.”

These are real, legitimate clinical findings. But they are outcomes, not causes.

When occupational health systems focus exclusively on this visible layer, they become reactive. Decisions are made to manage symptoms rather than risk. Workers are either removed from work longer than necessary or returned too quickly without meaningful exposure control. Symptoms may improve briefly, only to recur.

From the employer perspective, this manifests as repeated absences, lost productivity, and frustration. From the worker’s perspective, it feels unpredictable and destabilizing. From the clinician’s perspective, it becomes an endless cycle of reassessment rather than resolution.

This is not a failure of care.

It is a failure of depth.

Below the Waterline: Where Occupational Medicine Actually Works

Occupational Medicine specialists are not trained to simply decide whether someone is “fit” or “unfit.” That binary framing belongs at the surface. Our real work happens below the waterline, where clinical medicine intersects with exposure science, task analysis, and system design.

At the individual clinical level, this means understanding not only the diagnosis, but the exposure patterns that sustain it. In occupational dermatitis, the visible skin findings are driven by cumulative and often invisible factors: intermittent wet work, detergents and surfactants, glove occlusion, friction, and insufficient recovery time between exposures.

At the employer level, the same analysis reveals whether risks are truly controlled or merely assumed to be. Gloves may be provided, policies may exist, and training may have occurred—but without evaluating effectiveness, these measures can paradoxically worsen outcomes. Some controls increase occlusion, prolong exposure, or give false reassurance.

This is where structured qualitative occupational risk assessment matters. Hazards are identified, exposure patterns are assessed as they occur in real jobs, and risk is characterized in terms of persistence and relapse, not just acute injury. Control measures are then evaluated honestly, asking a critical question:

What actually reduces risk enough to allow safe, sustainable work?

The Iceberg Is Also a Timeline

The Razavi Occupational Health Iceberg is not only a structural model.

It is also a temporal one.

What appears above the waterline as clinical dermatitis and work restrictions is rarely sudden. It is the predictable endpoint of cumulative exposure over time, shaped by dose, frequency, task sequencing, and insufficient recovery.

Skin does not fail in a single shift.

Repeated wet work, detergent contact, prolonged glove occlusion, mechanical friction, and disrupted barrier recovery accumulate silently beneath the surface. Each exposure may appear tolerable in isolation. Over weeks, months, or years, they overwhelm the skin’s adaptive capacity.

This is why the tip of the iceberg is misleading.

By the time dermatitis becomes visible—prompting clinical visits, restrictions, or time away from work—the system has already failed repeatedly below the waterline. Exposure patterns were not recognized early. Cumulative dermal risk was underestimated. Control measures were assumed effective rather than tested. Task modification and accommodation were delayed until symptoms forced action.

Time is the multiplier that turns unmanaged exposure into disease.

Fitness-for-Work decisions that focus only on the visible condition treat a snapshot. Occupational Medicine evaluates the trajectory: how long exposures have occurred, how often recovery is interrupted, how controls perform in real work, and whether the system is learning or repeating itself.

A Clinical Story That Could Have Gone Either Way

In clinic, I recently assessed an individual with occupational irritant contact dermatitis working in a white-collar role that still involved intermittent wet tasks and routine glove use. On the surface, this appeared simple: a visible skin condition with an obvious recommendation to remove exposure.

That would have addressed the tip of the iceberg—and guaranteed recurrence.

Instead, the assessment focused below the waterline. Together with the worker and the employer, we clarified which exposures actually mattered, how often they occurred, and which controls were helping versus harming. Progressive fitness-for-work parameters were implemented. Specific glove systems and skin-barrier strategies were trialed in real work conditions, not on paper.

The outcome followed the logic of the iceberg. Symptoms stabilized. Confidence improved. Restrictions were gradually lifted. The worker returned to full duties—and remained there.

This was not luck. It was the predictable result of addressing both the clinical condition and the system sustaining it.

Two Futures, One Decision Point

Every Fitness-for-Work and Return-to-Work decision leads to one of two futures.

When decisions are made only at the surface, unmanaged risks persist. Exposure continues. Conditions recur. Employers relive the same problem under different circumstances.

When decisions are made with depth—accounting for time, exposure, recovery, and control effectiveness—treatment becomes prevention. Individual recovery aligns with organizational learning. The loop closes.

The Real Value of Occupational Medicine

FFW and RTW are not binary determinations.

They are dynamic risk-management processes operating across clinical and organizational boundaries.

Occupational Medicine specialists are trained precisely for this intersection. Not to choose between work and health—but to design systems where both are sustainable over time.

That is the difference between managing the tip of the iceberg and changing what lies beneath it.
